Summary

Within Santa Barbara County's unincorporated Coastal Zone, County Code Sec. 35-139 requires every exterior light fixture to be hooded and bars any unobstructed beam from shining onto a residentially zoned or developed property or an environmentally sensitive habitat area. Four community plan overlays, Summerland, Goleta/Eastern Goleta Valley, Montecito and Gaviota Coast, add stricter shielding and curfew standards on top of this countywide baseline.

City-specific rules exist: Santa Maria has its own light trespass & shielding rules that differ from Santa Barbara County's county-level regulations. If you live in Santa Maria, check the city-specific page instead.

All exterior lighting shall be hooded and no unobstructed beam of exterior lighting shall be directed toward any area zoned or developed residential, or toward any environmentally sensitive habitat area. No lighting shall be so designed as to interfere with vehicular traffic at any portion of a street. Division 13 (Summerland Community Plan Overlay), Division 14 (Goleta Community Plan and Eastern Goleta Valley Community Plan Overlay Districts), Division 16 (Montecito Community Plan Overlay District), and Division 17 (Gaviota Coast Plan Overlay) include additional requirements.

Full Breakdown

' The section also bars any exterior fixture from interfering with vehicular traffic on a street. Because this sits inside the Coastal Zoning Ordinance, it does not reach the incorporated cities of Santa Barbara, Santa Maria, Lompoc, Goleta, Carpinteria or Buellton, each of which enforces its own lighting code, and any new outdoor fixture in the Coastal Zone still needs a Coastal Development Permit under Section 35-169. The code's own glossary (Sec. 35-58) defines light trespass as 'Artificial light that produces unnecessary and/or unwanted illumination offsite including skyward or on a sensitive habitat,' and distinguishes fully shielded, partially shielded and unshielded fixtures.

Four community plan overlays layer stricter rules onto Sec. 35-139: the Eastern Goleta Valley Community Plan Area (Sec. and sunrise except while the business is open. Fixtures installed before that date are grandfathered out of the shielding mandate but still must meet the other standards. The Summerland, Montecito and Gaviota Coast overlays (Divisions 13, 16 and 17) impose comparable added requirements reviewed by the Planning and Development Department and the applicable Board of Architectural Review.

Violations & Fines

A light trespass violation is enforced under Section 35-185.5 (Cumulative Remedies and Penalties) of the Coastal Zoning Ordinance. A first infraction draws a fine up to $100, a second within a year up to $200, and each further violation up to $500. Repeat offenders can be charged as a misdemeanor punishable by a fine of $500 to $25,000, up to six months in County jail, or both. The County may also seek a civil penalty of up to $25,000 per day the violation continues, plus injunctive relief and abatement through County Counsel or the District Attorney.

Frequently Asked Questions

Does the county's light trespass rule apply inside the city of Santa Barbara?
No. Section 35-139 is part of the Coastal Zoning Ordinance, which governs unincorporated Santa Barbara County only. The cities of Santa Barbara, Santa Maria, Lompoc, Goleta, Carpinteria and Buellton each enforce their own lighting rules under their own municipal codes.
What exactly counts as light trespass under the county code?
The code's Sec. 35-58 glossary defines it as artificial light that produces unnecessary or unwanted illumination offsite, including light directed skyward or onto a sensitive habitat area. Section 35-139 bars any unobstructed beam from reaching a residentially zoned or developed lot or an environmentally sensitive habitat area.
Do all outdoor lights in the unincorporated area have to be fully shielded?
Section 35-139 only requires fixtures to be hooded with no unobstructed beam toward residential land or sensitive habitat. Full cutoff shielding is a stricter add-on that applies in specific community plan overlays, such as Eastern Goleta Valley, where fixtures installed after December 14, 2017 must be fully shielded.
What happens if a property owner ignores the lighting standard?
The County can cite an infraction starting at a $100 fine, escalating to $500 for repeat violations within a year, or pursue a misdemeanor with fines up to $25,000 and up to six months in jail for repeat offenders, plus civil penalties up to $25,000 per day.
